I agree@Wookie

Answer 23

It's how I learned. You have 81, you can draw a line on each side of the number of the numbers that go into and simplify from there

Answer 24

The initial question doesn't seem valid to me, because you CAN'T simplify 81.
81 is a whole number, written the way it is.

You can re-write it as a product of prime numbers, or write it as some exponent of 3 (3^4), or, you can write it as 9^2 or anything... but not to SIMPLIFY it.

Answer 25

Oh I thought 81 could be simplified. My bad!

Answer 26

It can

Answer 27

You just simplified it..

Answer 28

Is 81 really a whole number Solomon Zelman? Because if it can be broken down to 3*3*9 then 81 isn't a whole number and it can be broken down.
